OK, here are 2 shots comparing the 600 and 650. I had to dig up my 600 to take its shot. I used PDAReach and Snagit to get the pictures. All I can say is, OMG! I have no idea how I used to use the 600. The screen that I used daily now just looks unusable!

For those interested, this map shows the MIT campus in Cambridge, MA.

Oops, I'm sorry. I forgot to say that the 650 is still a piece of junk that's good for nothing
